Title: Method and apparatus for optimizing the layout and charge maps of a flowline of pick and place machines
Inventor: SCHAFFER JAMES DAVID
IPC: G06F15/18
Filed: 1997-10-30
Abstract: An apparatus uses a computer-controlled algorithm that enables production of high-quality layouts and charge maps or set-ups for arbitrary printed circuit boards for electronic components placement machines alone or as one of many in a production line. A class of algorithms known as genetic algorithms employing an initial population of chromosomes are used. Each chromosome represents a set of parameters that control how a layout and charge maps are generated. Problem descriptors, based on one time code are generated. An adaptive searcher searches parameters and generates trial solutions as chromosomes and a heuristic layout generator interprets these chromosomes to generate the layout and charge maps using the problem descriptors.

Abstract: A connector system is provided which enables a first connector (12), especially
a rectangular one, to be quickly locked and unlocked from a second connector
(14). A button (70) of a locking device (60), lies at a side (72) of the first
connector housing (30), so access to it is not greatly limited by conductors (34)
extending from the rear of the first connector. When the button is depressed, it
operates a mechanism that allows retraction of lock balls (100) to unlock.
Depression of the button causes a plunger (110) fixed to the button to move
deeper into a slot (122) of a shaft (90) and to press against an inclined wall
(112) at an end of the slot to move the shaft.

Abstract: This invention is to provide an apparatus for
separating a substrate having a porous layer at the
porous layer. A bonded substrate stack (101) having a
porous layer (101b) is supported by substrate holding
portions (120, 150) while being rotated. High-speed,
high-pressure water (jet) is ejected from a nozzle (102),
so the jet is injected into the bonded substrate stack
(101). The substrate holding portions (120, 150) hold
the bonded substrate stack (101) such that the bonded
substrate stack (101) can expand at its central portion
due to the pressure of the injected water. This
efficiently applies a force (separation force) that acts
outward from the inside of the bonded substrate stack
(101).

Abstract: Gamma cameras and positron (PET) cameras use scintillation detectors to detect radiation from the body. However, when the number of radiation particles that strike the detector is very high, the chance that signals from two or more individual particles will pile up in the detector (to produce one erroneous, larger signal) is high. This problem is common to all applications using scintillation detectors. The present invention discloses methods and apparatus to prevent and correct for this problem. Results from a circuit according to the present invention show at least a 10 fold improvement in the maximum detection-rate limit over the conventional method.
